I IMPPROVED APPARATUS FOR EVAPORATING AMDl yDEFECAl'l-NG SORGHUM-JUICE.

Specification forming part of Letters Patent No. 36,4iv7date'd Scptenibcr 16, 1862.

.declare the followingto be a full and accurate ldescription thereof, reference being had to the accompanying drawing, and tothe letters of reference marked thereon.

l The said invention consists of a double evaporatingpan to be made of copper, zinc, or galvanized iron, to be from 4five vto ten feet in length, and from two to three' feet in width,` and each to-be placed over a double furnace made of brick and-mortar for permanent use,

off out ofthe-pan A through the strainer G by the *faucet S into the receiver P in thelower pan. ,Thequantiftyofj uice thus continuously let into .andout Aof, the p'an A is regulated by the use of the said faucets, keeping aluniforni tubes marked-o o o o o o, and after being boiled therein until reducedto the' desired consistency 'passes out-lof said pipes or tubes into the compartment L in the lower p an,.fron1 whence itjis drawngoff, )through the faucet marked t, continuously into 'a vessel, the sirup in the receiver P, and while passing, through fthe or a portable furnace' made, of sheet iron or rapidity with which itx-passes through said.

metal. 1

The marked A in the accompanying y drawing is elevated-on the furnace', sothat'the lower edge or bottom thereof is even with the Vupper edge ofthe pan B,When'b'oth are placedv in their proper positions in the furnace.v i The `loyver pau, B, is divided by partitions extending across the-same into four compartmentsof unequal size. Aiaucet5fS, isinsertedinto the `pan .Aat .the lower edge of the side thereof, next to the pan B, and immediately overthe receiver P, for the pnrposeof conveying' the ,juice otsirup fronti the pan A to the Vreceiver F inthevpanB.' A' numberf lofftubes or pipes (marked o o 0 u-Dslextens from the receiver flJ tothe compartment Inl'uach, `of said pipes.

or tubesopening at'the ends thereof into rel-v ceiver and compartment L, saidpipes or tubesfto-,be made of copper, `zi'nc', .or` galvan;` pan B is putinto-the pariA A, and-.mixed with;

ized iron,having`a diameterof from one to two inches, and-to ,be from six to eight in iiirnier.l

. The .said pans are each placed horizgntauy im the' furnace` and nearly contiguous to leach,` the'pan A being elevated abovejthe-panfB, as. aforesaid. f'lh'e raw juice of Lth'e sorghum is irst let into the. panzmarkedA i-n'theaccomf panying drawing from atub or other vessel through a faucet, andiheppan being placed overl a rapid iren .the 4furnace,;th,e juice is iirstboiled in said pan to a proper consistency and until the extraneous matter or scum is brought to th'surface and skimmed ofi'. The raw `iuice is thus continuously let into.4 the pan A from the tub' or other vessel, and after boil# ing insaid pan until it is reduced to a ccitaln consistency itis continuously thereafter drawn pipes or tubesvto be gov'ernedbythe quantity of the compartment; L. `Before the juice or Sirup islet into'the receiver l? from -pan A a B, by meansof-a faucet from a vessehand, pass:

The raw j uiee is thuscontinuously let'into the .panvB, fand whileiu said pan kept constantly boiling, 'and is continuoslylet out' through the faucet m 'into a vesselyandfroin thence the juice thus boiled to a certain consistency in the raw'juice therein,` so--as to allowit topass ing or burning. The object inhaving thesir- .up to pass through and boil in said pipes or tain rapid evaporation thereof after being reduced to a certainconsistenoy Without danger quantity thereofin panA, From the receiver l. the juice or sirup passes into'the pipes orv pipes `or tubeso o' o oo andinthe coinpart-- ment L to be kept constantly'boiling, and thev continuously let into 'the receiverl P and out 'quantity of rawjuice is let into the lower pan;
